Answer:

The approximate lateral area of the prism is [tex]831\ in^{2[/tex]

Step-by-step explanation:

we know that

The lateral area of the prism is equal to

[tex]LA=PH[/tex]

where

P is the perimeter of the base of the prism

H is the height of the prism

Find the perimeter of the hexagonal base

Remember that the area of the hexagonal base is equal to

[tex]A=\frac{1}{2} P(a)[/tex]

where

P is the perimeter

a is the apothem

we have

[tex]A=346.41\ in^{2}[/tex]

[tex]a=10\ in[/tex]

substitute and solve for P

[tex]346.41=\frac{1}{2} P(10)[/tex]

[tex]P=346.41/5=69.282\ in[/tex]

Find the lateral area

[tex]LA=PH[/tex]

we have

[tex]P=69.282\ in[/tex]

[tex]H=12\ in[/tex]

substitute the values

[tex]LA=(69.282)(12)=831\ in^{2[/tex]

Answer:

Your answer is 7.0

Step-by-step explanation:

If the circles are congruent and RQ measures 35.6, then so does CB.  That means that half of it (the radius XD which measures 26 cuts the length of CB in half) is 17.8.  If the base of that right triangle is 17.8 and the hypotenuse is 26, then Pythagorean's Theorem tells us that the height of the triangle is 18.95151709.  Subtract that from the radius length of 26 and you'll have the length of DE

The value of length ED would be, 7.0

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

⊙X≅⊙Y

And, Length of RQ = 35.6

Now, We get;

⇒ CB = RQ = 35.6

Hence, EB = 1/2CB

                 = 1/2 (35.6)

                 = 17.8

Applying Pythagoras theorem,

⇒ XE² = XB² - EB²

⇒ XE² = 26² - 17.8²

⇒ XE² = 19

Thus, The length of ED is,

⇒ ED = XD - XE

⇒ ED = 26 - 19

⇒ ED = 7.0

Therefore, The value of length ED would be, 7.0

Answer:

5/2 kg

Step-by-step explanation:

The ratio here is 2:6.  2 plus 6 is 8.

Then (2/8) times 10 kg represents the amount of compost needed; that comes to 20/8 kg, or 10/4 kg, or 5/2 kg.

Gabriel should use 2.5 kilograms of compost to create a 10-kilogram mix that has a ratio of 2 parts compost to 6 parts potting soil.

Gabriel is making a mixture for a special plant which requires a ratio of 2 parts compost to 6 parts potting soil. He aims to make 10 kilograms of this mix in total. To calculate the amount of compost he should use, we first have to find the total number of parts in the mix:

Add the parts of compost to the parts of potting soil: 2 parts (compost) + 6 parts (soil) = 8 parts (total).

Determine the weight of each part: 10 kilograms (total mix) / 8 parts = 1.25 kilograms per part.

Multiply the weight of each part by the number of parts for compost: 1.25 kilograms per part × 2 parts (compost) = 2.5 kilograms of compost.

Therefore, Gabriel should use 2.5 kilograms of compost for his special plant mix.

Answer:

Step-by-step explanation:

20 x 2 = 40 40 x 2 = 80 80 x 2 = 160 x 2 = 320 320 x 2 = 640 after 5 days on may 6 it will surpass 500 meters.

The oil spill, doubling in size each day from an initial 20 square meters, will exceed 500 square meters on the 6th of May.

Based on the information provided, let's calculate how long it will take for the oil spill to exceed 500 square meters if it doubles in size each day starting from an initial size of 20 square meters. On May 1, the spill is 20 square meters. On May 2, it would be 40 square meters (20*2). If we continue this pattern, we can find the day the spillage area will exceed 500 square meters:

Therefore, the area of the oil spill exceeds 500 square meters on May 6.

Step-by-step explanation:

If you take 7.6 and multiply it to 16,412.05 (.076)(16,412.05), you get 1,247.32. You then add the overhead cost of 105 to get 1352.32. (Apex verified too)

The drivers insurance premium is:

                $ 1352.3158

The probability of a driver getting into an accident is 7.6%.

The average cost of an accident is $16,412.05.

This means that the expected amount that will be paid to each of the driver by the company on accident will be:  0.076×16412.05

                                                       = $ 1247.3158

Also, the overhead cost for an e company per insured driver is $105.

This means that the insurance premium of driver is:

       =   105+1247.3158

     =    $ 1352.3158

Answer:

y = 13

Step-by-step explanation:

If it's a parallelogram then its consecutive angles are supplementary (add up to 180°).

6x - 12 + 132 - x = 180°,

5x + 120 = 180

5x = 60

 x = 12

6x - 12 = 6(12) - 12 = 72 - 12 = 60

Parallelogram, opposite angles are equal

so

6y + 18 = 6x - 12

6y - 18 = 60

6y = 78

  y = 13

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form  [tex]y=ax^2+bx+c[/tex] , It is vertical (opens up or down).

Because the variable "x" is squared.

If  "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

[tex]f(x) = 2x^2+5x-4[/tex]

Which can be rewritten as:

 [tex]y = 2x^2+5x-4[/tex]

Therefore, it is vertical, because it has the form:  [tex]y=ax^2+bx+c[/tex]

You can observe that the value of "a" is:

[tex]a=2[/tex]

Then, since "a" is positive, the parabola opens up.

-40*.15 + 150*(1-.15)= 121.50

Given the probabilities of sunny and rainy days and the respective profits, the Sudsy car wash's expected net profit per day, considering the rain probability, is $121.5.

The subject of the question is about Expected Value, a concept in Probability Theory. Considering the Sudsy car wash's situation, we know that it loses $40 on rainy days and gains $150 on sunny days. The probability of having a rainy day is given as 15%, which means the probability of having a sunny day is 85% (100% - 15%).

The expected value of the net profit can be calculated by the formula for Expected Value: E[X] = ∑[x*P(X=x)]. In the context of this problem, we can write out the expected value E[N] of the net profit N as E[N] = (-$40 * 0.15) + ($150 * 0.85) = -$6 + $127.5 = $121.5. So, it is expected that the Sudsy car wash will have a net profit of $121.5 per day, on average.

Answer:

d

Step-by-step explanation:

30% of 50 is 15 because 30 % means 30out of 100

and if you half 100 you also half 30

Valentina, with a 30% probability, can expect to draw a blue marble 15 times out of 50 draws. This is calculated by multiplying the total number of draws by the probability of drawing a blue marble.

The question revolves around the concept of probability. The probability of an event is the measure of the likelihood that the event will occur. In Valentina's case, she has a 30% chance of drawing a blue marble. Therefore, if she were to draw a marble 50 times, we would expect her to draw a blue marble 30% of those 50 times. Probability is often expressed as a fraction or decimal, and in this case, 30% translates to 0.30 in decimal form.

To calculate how many times we can expect Valentina to draw a blue marble, we multiply the total number of draws (50) by the probability of drawing a blue marble (0.30).

So, 0.30 * 50 = 15.

Therefore, Valentina can expect to draw a blue marble 15 times out of 50 draws.

Since the triangles are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{4x+12}{15}[/tex] = [tex]\frac{32}{8}[/tex] = 4, thus

4x + 12 = 4 × 15 = 60 ( subtract 12 from both sides )

x = 12
